It' has the form of ashaft that is mounted mbearings in a suitable support or member 11. 1tmay be provided with a belt pulley or other transmission device 12whereby to rotate the same.

14 designates v.the `intermittently driven' `element, which vhas theform of a shaft that 1s mounted in bearings inthe member 11, and whlchmay be connected to any suitable mechanism that is designed to beoperated by an intermittent rotary motion.

- 15 designates a gear wheel which is keyed or otherwise non frotativelysecured to the 70 shaft 10.' Said gear wheel 15 meshes with a secondgear wheel 16 which, as herein shown, is keyed to a stub shaft 17 thatis' rotatablymounted in-the Vmember 11.

v v18 designates a disk which is mounted on the shaft 14 and is providedwith a hub 19; said disk being secured to the shaft by 'means of a pin20 extending through the huband shaft.

@21 'desi nates a track member that -isgse4 'cured to t e innerface ofthe disk 185 as by lmeans of thev screw bolts'22. 'Said track' -lnemberis provided with a' plurality of radial channeled'tracks or grooves 235there. being six of such tracks `or grooves shown. Saidchanneled tracksor grooves are open at their outer ends andare bounded attheir sides byparallel flangesor ribs 24. They vopen 'at their inner ends intoa-central open l anges- 240i adjacent radial tracks are connected attheir inner ends by Athe curved portions l2 6, constitutingcontinuations of said flanges or' ribs. The gear wheel 16 lis providednear. its periphery with astud 27 which carries a loosely mounted roller28 vthat extends toward and is adapted to travel in said channeledtracks 23. The disk 18 is provided with a V-shaped groove 2 91 in Whichalike shaped tWo-part-brake'ele- '-100 Y ment 30, 30 j made of rubber. orother sui t" able -fyielding friction material. The sald groovegby'meansof the jaws 31, 31 which are pivoted to eachother by means of thepivotf` lin1 .32 whichextends through the hinge" lugs 33 of said jaws.Saidjaws` are` provided `diametrcally- 'opposite the hinge With parallellugs-341, 34 to one of which 1s latlixed'va' screw-threaded bolt 35which ex 110 stantially one-half of its revolution said bearing roller.27 passes from a point at the outer end of one track (the position shownin Fig. 1) to the inner end of the track to impartto saidv track memberand the disk 18 and shaft'14 associated therewith a partial rotationinthe direction indicated bythe arrow, and during the. latter half of therevolution of said bearing roller v28 lit travels outwardly through thenext adja cent lor rear track 23, relatively to the direction ofrotation of the track member 21. The speed ofthe driven part, to wit,the shaft 111, is greatest while the bearing roller 28 is travelingthrough the outer ends of' the tracks, such speed gradually decreasingas the bearing roller approaches the inner ends of the tracks andinallybeing brought to a rest to effect the proper'pause or dwell as thebearing roller passes from one track to an adjacent track. During suchtime as the bearing roller 28 is `engaged with the curved connecting ribor 'ange 26, the said latter iian e is substantially concentric with theaxis 0% rotation of the gear wheel 16 so that, as a result, said bearingroller 28 imarts no movement to the track member. uring this periodtherefore the movement of said track member and the shaft .14 con nectedvtherewith is arrested-to give theI proper pause or dwell to said parts,notwithstanding the continuous movement of the bearing roller 28. in acircular path. As soon 4as the said bearing roller leaves the concentricV'portion of the 'curved connecting rib 26 and moves outwardly into the51)lneXt rearward channeled track, rotary movement of said track Vmemberand, the parts connected therewithy begins and centinues while thebearing roller 1s traveling .outwardly through said track to the outerend thereof and inwardly to the inner end of the latter track. It willthus be seen that the track member and the parts connected torotate'therewith are brought to a fvery gradual stop or pause and thatthe movement of said track member is gradually resumed after such pauseand gradually accelerated. By reason ofthe fact that the said trackmember is traveling at its slowest speed just before it is brought to afull stop, there is less likelihood of sa1d adapted track member and theparts rotating therewith overrunning the desired stopping point whenbrought to rest. Also by reason of`the fact that the parts are broughtinto motion very gradually after the ,pause or dwell thereof,'there isoccasioned no shock or jar when said parts are thus brought into motion,so that the'said secondary or intermittently rotated part may beconnected to and operate delicate mechanism without danger of injuringthe same.

The brake consisting of the members 30, 30 and the jaws 31, 31 isprovided to avoid `all likelihood of the parts overrunning when theparts are to be brought to rest.

In the organization of the mechanism here shown, and which issubstantially the arrangement of the mechanism employed in the wrappingmachine hereinbefore referred to, it becomes convenient to apply 'thepower to the shaft 10. In some instances, however, the shaft 17 maybecome the primary driven element, with the same results in operation.

'I claim as my invention 1. A mechanical movement comprising a drivenelement, a series of radial tracks thereon with adjacent tracksconnected with each other at their inner ends, a rotary,driv ing elementarranged with its axis radially within the periphery of the drivenelement and a bearing stud arranged eccentrically on the driving'element to travel through said tracks.

2. Mechanism for translating the continuous rotary motion of a drivingelement into an intermittent rotary motion of p a driven element, with apause or dwell' between'such intermittent motions, comprising a primaryshaft with means for rotating the 'j shaft, a secondary shaft, a memberthereon having a plurality .of radial tracks which are connected attheir inner ends by curved portions, a bearing member rotatinU with andeccentric to the primary sha; and to travel inwardly through one track,around said curved connecting portion and `outwardly through anadjacent" track, the curved connecting portion between adjacent tracksbeingrconcentric to the driven shaft while the bearing roller is passingardund the same.

3. Mechanism for translating the continuous rotary motion of a drivingelement into an intermittent rotary motion of adriven element, with apause or dwell between such intermittent motions, comprising a primaryrotative shaft with means for rotating the shaft, a secondary shaft, amember thereon having a plurality of radial' channeled tracks with sideflanges, the ianges of adjacent tracks being joined by a curvedco'nnecting flange and a bearing member rotating with and eccentric tothe primary shaft and adapted to travel inwardly through o1"ie"'trackaroundl said curved connecting rib and outwardly through an adjacent track.

4. Mechanism for'translating the continuous rotary motion of a drivingelement into 'an intermittent rotary motion of a driven element, with apause or dwell between such .intermittent 4mot-ions, lcomprising adriving Ftation of the said -second gear wheel, to pass inwardly throughone track, around said connecting portion and outwardly through 20v anadjacent track.

5.V Mechanism for translating the continuous rotary motion of a drivingelement into an intermittent .rotary motion of a driven element, withaopause or dwell between such intermittent motions, comprising a drivingshaft, a gear wheel thereon, a second shaft, j a gear wheel thereonmeshing with the rstj" gear wheel, a third shaft, a member thereon?"`having a plurality ef radial tracks which are united 'at their innerenlds by curved connecting portions, a bearing member car- 1 ried by thesecond gear wheel and ecl centric thereto 'and adapted, during eachrotation of the said second gear wheel, to

pass inwardly through one track, around said connecting portion andoutwardly through an adjacent track, and a brake device associated wi'ththe driven shaft to prevent the overrunning of said shaft.
